LIQUID SPRAYER Filed Sept. 15, 1930 Patented Feb. 20, 1934 UiTiE. STATS PAT Application September 15, 1930, Serial No. 482,104, and in Germany August 4, 1930 12 illaims.

My invention relates to a spray or atomizer for liquids. It is intended for containing and spraying small quantities of liquids, particularly for perfumes (scents, eau de Cologne, mouth Wash,

etc.,) and which, after use or after emptying the contents, may be simply thrown away as worthless when the small quantity of liquid contained therein has sufficed for use on one occasion only.

The spray in accordance with the invention consists substantially of a closed hollow capsule of a double calotte shape, made of materials such as aluminium sheet, tin foil, rather resilient but fairly soft metals, but also of celluloid, gelatine, film composition, acetyl-cellulose, paper covered with metal foil, in short, all materials which may be easily opened or punctured with a pricking element, such as a needle, and then deformed or squeezed flat by pressure from the finger, so that the contents of the original hollow interior is forced out of the punctured hole in spray form. These capsule sprays are suitable particularly for refreshing the face, head, hands and other parts of the body or also for containing single issues of mouth wash for rinsing the mouth etc., after fatiguing marches, on journeys or after other bodily exertions.

The invention will be better understood by referring to the accompanying drawing in which Figs. l-l show some practical embodiments of the spray in accordance with the invention.

Fig. 1 being a side elevation of the first example, in which the pricking member is arranged inside the spray,

Fig. 2 a vertical section through Fig. 1 and Fig. 3 a vertical section through a completely evacuated capsule according to Figs. 1 and 2.

Fig. 4. shows a plan of the holder for the pricking element according to Figs. 1 and 2 and Fig. 5 a side elevation of the pricking element itself.

Figs. 6 and '7 illustrate a modified example of the invention,

Fig. 6 being a side elevation of the modified spray, showing the holder for the pricking meme ber in section, whilst Fig. 7 is a plan of the example according to Fig. 6.

In the two different examples shown in the drawing, the capsule-form liquid container consists of two hollow halves m the shape of a calotte or spherical segment, that is, a top half a, and a bottom half 2). Both halves are joined together liquid-tight at the base by folding, welding, adhesion, solution or the like.

In the example according to Figs. 13 this union is made by the horizontal flange a of the top half a, being placed on the horizontal flange 5 of the bottom half I), with a thin packing ring e, of rubber, cork, parahined paper or the like interposed therebetween, after which a turned over flange b unites the two halves a and b to each other.

The capsule a, b is opened by means of a pricking member (1. This member may consist of an ordinary pin whose head d rests in a cavity a provided in the middle of the top half a, whilst the point d may rest in a corresponding cavity b of the bottom piece 22. By exerting a pressure on the top portion a in the direction of the axis of the pricking member 01, the point d punctures the wall of the container at the cavity be. With continuing pressure, preferably exerted by the thumb whilst the index and middle fingers are held against the surface of the bottom piece 1), each side of the indentation b the liquid contents are emptied through the punctured hole, as the top cover a, is deformed. When this is done, the top half a, as will be seen in Fig. 3, rests flat against the bottom portion b, so that the very last remains of the liquid are forced out through the orifice. The capsule thusemptied, is then thrown away as worthless.

The capsule half b, is filled of course, before the top cover half a, is joined on to it. When the cover a, has been placed on the filled bottom half 2), the previously vertical flange 19 has its top portion pressed hat on the edge a of the cover by the descent of a pressure die, Whilst an interposed packing ring ensures that a tight joint is effected.

In order to facilitate the insertion of the pricking member d, in the capsule portions a, b when the cover portion is placed upon the filled bottom half b, and also to fix the position of the pricking member, it is possible to use a threearmed needle holder 0, which is provided in the centre with an aperture 0 which corresponds approximately to the diameter of the pricking member d, but is smaller than the head d of the same. fhis holder c is preferably adapted to the segmental shape of the cover portion a, that is, the arms 01mg closely to the curved shape of the inner wall of the cover portion a; The ends 0 of the holder c are fixed with respect to the bottom portion b, by fitting in an annular recess b of the latter. Whilst the bottom portion I) is open, the holder 0, with the pricking member d inserted in the hole 0 is laid on the bottom portion b, whereupon the top portion a is placed over and the two halves a and b then joined together.

Instead of the pricking member at, being placed between the parts a and b, the point (1 of the pricking member d, may also be inserted in a hollow a let in the cover a, whilst the head d of the pricking member is embraced by a cupshaped indentation 0 the ends c of the arms c of the holder being clipped over the flanged edge b With this type, the spray is used by pressure being exerted on 0 d in the axial direction of 05 thus piercing a hole in the hollow a, of the cover portion a. The ends 0 of the arms c clipping the flanged rim b are then deformed so that the entire holder 0 together with the pricker d can be taken 01? from the portions a, b and discarded. Then the bottom half b, is pushed against the top half at, until its shape conforms to that of the top half and all the liquid from the bottom part b, has been squirted out through the pierced hole.

It is advisable to shape the point (1 of the pricking member (it somewhat fiat like a chisel, so as to obtain a long pierced hole from which the liquid may issue at each side of the round stem of d, easier than if the point were conical as in an ordinary pin.

Of course, the outer shape of the container may be of a form other than segmental, without the invention having to be modified in any es sential details.
